At the end of the day a DVB-S STB is DVB-S STB and so the answer to whether a Sky box can receive stuff from other satellites is yes - but there a BIG however.
You won't be able to use the Sky menu structure and so you will need to add all the channels manually. Sky+ will not work.
You would be better off buying a proper Free to Air Receiver for about fifty quid from Lidl, Aldi or Maplin. (The latter may even have PVRs.)
